Jason Isringhausen has been impressive this spring despite being sidelined briefly by arm problems, but David Waldstein of the New York Timesreports that the Mets have asked him “to remain in extended spring training for a week or two to increase his arm strength and reassure them that his elbow is healthy.”

Isringhausen previously said that he wouldn’t be willing to pitch at Triple-A, but extended spring training might be a different situation. For now he told Adam Rubin of ESPNNewYork.com that “there has been no formal request” from the Mets, saying: “All we’ve done is talked. No one has asked me to do anything.”

According to Rubin the Mets are trying to figure out a way to keep Isringhausen, Manny Acosta, and Blaine Boyer in the organization.

UPDATE:Rubin says Boyer made the team, Acosta was designated for assignment, and Isringhausen is deciding whether to stay behind for two weeks.

The Oakland Athletics ballpark saga has dragged on for years and years and years. They’ve considered San Jose, Fremont and at least three locations in Oakland as potential new ballpark sites. The whole process has lasted almost as long as the Braves and Rangers played in their old parks before building new ones.

In the past several months the Athletics’ “stay in Oakland” plan has gained momentum. At one point the club thought it had an agreement to build a new place near Peralta/Laney College in downtown Oakland. There have been hiccups with that, so two other sites — Howard Terminal, favored by city officials — and the current Oakland Coliseum site have remained in play. There are pros and cons to each of these sites, as we have discussed in the past.

One consideration not mentioned before was mentioned by team president David Kaval yesterday: sea level rise due to climate change. From the San Francisco Chronicle:

Kaval mentioned twice that the Howard Terminal site would have to take into account sea-level rise and transportation concerns — and he said there have been conversations with the city and county and the Joint Powers Authority about developing the Coliseum site.

The Howard Terminal/Jack London Square area of Oakland has been identified as susceptible to dramatically increased flooding as a result of projected sea level rise due to climate change. On the other side of the bay both the San Francisco Giants and Golden State Warriors have had to consider sea level rise in their stadium/arena development plans. Now it’s the Athletics’ turn.

Fifteen of Major League Baseball’s 30 teams play in coastal areas and another five of them play near the Great Lakes. While some of our politicians don’t seem terribly concerned about it all, people and organizations who will have skin the game 10, 20 and 50 years from now, like the Oakland Athletics, are taking it into account.
